Curveball!

Curveball is kind of a 3D ping-pong, only that the ball's trajectory
will curve depending on the way you hit it with the paddle.

The controls are simple: click the ball to serve, then move the mouse to hit
the ball when it comes back.

There two types of bonuses: the time bonus, and the angle bonuses. The time
bonus is a set amount for each level which decreases while the ball is in play;
the angle bonuses, Accuracy, Curve and Super Curve, are approximately 100, 50
and 150 respectively, and change depending on the curve and angle.
